Application filed July 7, 1806. Serial No. 325,112.

To all 'whom it may concern:

Be 1t known that I, PrnLIeDnvnm-:nx JOHNSTON, a citizen of the United States,

residing in Cold Spring, county of Put .production ofa device for vaporizing and atcmizing heavy oils, or a mixture of heavy oils and water, in connection with internal combustion engines, in which the oil will be more completely vaporized and more intimately mixed with thewater and air than has heretofore been possible.

The invention also relates to improve ments in details or construction as will more fully appear from the following specification.

I attain the objects ofiny invention by the mechanism illustrated in the accompanying drawings, in which Ifigire l is a longitudinal sectional view of a i aporizer embodying my invention, and Fig. 2 is a horizontal sectional view of a portion of saine.

In both views like parts are designated' by the same reference characters.

In carrying ont myinvention I providemeans for injecting oil and air'in concentric streams, the oil preferably sarroumlcd by an annular stream of air, with a stream of air within the center of the stream of oil.

The angles at which the several streams are' discharged are such that the'oil is thoroughly broken up between the two streams ot air.

'This' broken up oil mixed' with air is then met by a stream et' water at an angle, wherelby the mixture of oil, air and water is rendered complete.

In the drawings, the character l represents the oil passage. vWithin this passage is an air passage 2, and surrounding it a sccond air passage 3, The passage t'or the water is indicated at Il-,andis shown at right angles to the other passages, although the 'angie may vary, is obvious.

The structural means of carrying out th invention, is shown as Aconsisting of a body 5, having a flange 6, which may be bolted to the combustion chamber. This body has a threaded opening in which a tubular body lhis tubular bod -carries the air'passage 3. The tubular body 7 has an extension 8,' containing 'the oil passage 1. A

.tapering passage.

of the engine..

spindle 9 which carries a portionof the air passage 2, slides within the extension 8.

The rest of the air passage in the form of a nipple which extends out at an angle to,

rIhe inner end ofthe spinthe extension 8. dlei) is beveled as shown, and closely engages with the beveled opening formed within the projection l0 of the 'extension 8, suchV projection lying within the hollow portion of ,the tubular body 7. tension l0 is beveled as shown, and the corresponding end of the hollow of the body 7 is beveled also, but at a di'erent angle, the space between the two forming an annular By moving the spindle f) outward anV opening will be disclosed between it and the inner surface of the projcction 1 0, through which the stream oi' oil from the passage l, may be injected. The size of this opening may be varied by moving the spindle Seoutward or inward. The

spindle 9 is preferably moved by means of a lever li, carried upon a shaft l2 which is properly,connected to a source of governing. This shaft l2 is shown as mounted in a bearing on a support 13, which is` screwed to the extension 8.

rl`he passage 4, for the water. ends ina nozzle 14,'whieh is shown ati-ight anglesv to the other nozzle already described. This nozzle l-'l is beyond the other nozzles, and preferably extends about halt' way into a mining` passage l5, which conmluuicates with the interior of the combustion chainher. A slide valve 1G, is interposed in the mixing passage l5 so as to close the same at the proper time, during the explosion stroke The operation is as tollows:-Air under constant pressure is admitted through the passages 2 and 3, oil and water are pumped through the passages l and 14 by pumps which are timed to inject a quantity of oil and water at the proper interval during the operating cycle' of the engine. The valve i6 being open, and the back pressure within the combustion chamber sufficiently low, a stream of air will be driven inthrough the passage 2, in the form ofa solid pencil and a second stream of air will be driven through.

The end of this ex' Cyl and the beveled end of the projection 10. The opening between the spindle 9 and the projection l0, being suiiicient, owing to the .position of the rod 9, caused by the operation of the governor, the oil will be driven in by. the oil pump, and also partly by the injector-lilre action of the air. It will be noted that owing to the shape of the stream of air through the passage 3, and the stream of air through the passage 2, the oil will be' thoroughlybroken up and mixed with the air. At the same time the mixture of air and oil will 'meet the stream of water issuing from the nozzle 14, which stream of water will strike the opposite wall of the passage the spindle 9V intimately breaks up the oil which is driven and drawn in in the form of an. annular stream which strikingl the side Walls of the passage l5 is there mixed with the stream of water, The balance of the air 35fyinov'es at highjyelQCtyand is of high through the passage 3 will strike at a diithis 3rd day ofJuly, 19.06.".4 p readyfornicd-apd will further break it up."

ferent angle the mixture of oil and air al- At this place it will be understood it is met by the streaiii of water which preferably Pre-S sure, which striking the opposite Wall of the passage 1 5 will be there finally divided and thoroughly mixed with the oil and air.

Having now described my invention, what I claim is:

l. A vaporizer having an oil passage, and an air passage outside of it and an air passage inside of it, with a mixing chamber into which the said passages enter, the said chamber having a passage for `water entering it at an angle to the other passages.

2. A vaporizer having an oil passageand' an air passage outside of it andvanair passage inside ot' it, with a mixing chamber-into' which the said passages enter,'.the said chamber having a passage forwater entering it at right angles to the other passages. f

3. A vaporizer having means forintroducing oil into a closed chamber, means for introducin air, the Asaidlatter means including a lollow spindle, means controlled by the sliding of the 'spindle for'varying i the amount of oil introduced, and means for introducing Water Into the chamber at an angle to the air.

4. A vaporizer having an `oil passage, and A an air passage outside of it, and an air passage inside of it, in combination with means 'ectinfr water at an angle into the issuing ]et's o? air andpil.
